Siheyuan starts from a better life

Chapter 400, Small Engine
After I came back, I happened to meet some aunts in the courtyard at the entrance of the alley.

"Hey, Xiao Jiang, have you bought another one?"

"Yes, we just got married. The leader gave us a bicycle ticket. Why don't we go buy one now? Okay, ladies, you guys are busy first. We're going home first." Jiang Yan greeted and then took Jiang Sirui with him. Return home.

"Didn't this little Jiang have a car assigned to him? Why did he buy a bicycle?" An aunt in the yard next door looked at the jeep following Jiang Yan and said.

"Not only do they have big cars at home, but they also have three cars, but they don't drive them often. Only Zhuzhu and the others drive them," another aunt said.

"What do you know? Jiang Yan's family not only owns three cars, but almost everyone has a bicycle." The third aunt spoke to the sisters surrounding her with an arrogant look, as if this car belonged to their family. Same.

"Brother Jiang Yan, can you let me ride the bicycle my sister-in-law retired?" He Yuyu looked at the new bicycle in Jiang Sirui's hand with envy, and directly pulled Jiang Yan to ask.

She has seen Jiang Sirui's women's bicycle. Jiang Sirui usually rides it with more care. This bicycle is [-]% new.It's still quite stylish when riding out.

"Okay! From now on, this car will belong to Qin Qi." Before Jiang Yan could speak, Jiang Sirui spoke directly to He Yuyu, leaving only Qin Huairu with an envious look on his face.

"Daughter-in-law, it's okay. After you give birth to the baby, I will go to the boss to get you a bicycle ticket." Seeing his wife's envy, as Qin Huairu's big dog, He Yuzhu, who now loves his wife unrivaled, drove directly Finished.

"Forget it, it's too expensive. As long as you have one at home, it's fine. I can take it or not." Qin Huairu refused directly.

"Sister Qin, it's okay. I'll ask Brother Jiang to find one for you when the time comes. The bicycle I replaced was originally going to be kept at home. If you like the rain, I'll ask her to ride it first." Jiang Sirui, who was next to her, spoke directly. In my opinion, the ticket for a bicycle is not a big deal. If my husband can't get it, I will go to my uncle.

After He Yuyu returned to the house and put down his schoolbag, he couldn't wait to pull Jiang Sirui, and the two began to practice driving in the courtyard. Qin Huairu and the others looked on with surprise.

"Why are there so many dishes tonight?" Jiang Yan came to the living room and saw four cold dishes on the table. He Yuzhu and the others were still busy in the kitchen.

"Tonight, grandma asked me to invite three uncles over for a drink. By the way, I want to tell you about your wedding." Xu Damao brought over a plate of fried peanuts and explained to Jiang Yan.

After dinner in the evening, the three uncles from the courtyard came to Jiang Yan's yard together. When they saw Jiang Yan and the others cooking a table of delicious dishes, the three uncles were stunned.

"What are you still doing? Let's do it!" The old lady sitting on the main seat said directly.

Hearing the old lady's greeting, the three uncles sat down immediately, especially the third uncle Yan Bugui, and swallowed his saliva while looking at the dishes on the table.

In fact, Jiang Yan and the others did not prepare any special dishes. The only dishes they could bring out were a plate of twice-cooked pork and a plate of beef. The others were basically vegetarian dishes, but they were full of oil and water.

After Jiang Yan toasted each of the three men with a drink, the old lady told them about Jiang Yan's marriage.

Amidst everyone's congratulations, the first man asked: "Xiao Jiang, how do you plan to invite us to the yard?" When the first man asked, the old lady directly told the three of them what they had discussed before.

"It's better that the old lady and Mr. Jiang have considered it carefully. This is good. At least it doesn't leave any clues for others. The higher authorities do recommend that you don't eat and drink too much. Mr. Jiang has a high status and others are watching! If you are not careful, you will give others a clue. It’s a joke, but people sitting in the courtyard like this can’t say anything.” The second uncle, Liu Haizhong, spoke first.

"That's right, it's not easy for anyone these days." Yan Bugui also nodded repeatedly. There was no need to pay for this gift. He could have a free meal, and his family didn't miss it. There were six steamed buns in the family. According to Jiang Yan's family At the same level, this steamed bun has to be made with two noodles instead of two.

The old lady smiled from ear to ear and said: "Zhonghai, you take charge of this matter and help Xiao Jiang to organize it, and you two help Zhonghai."

After speaking, he pointed at the second uncle and the third uncle, and the two uncles naturally nodded repeatedly.

"Old Liu, please stay for a moment and come to my study." After the show, Jiang Yan directly stopped Liu Haizhong who was about to leave.The other two people heard this and knew that they had something to discuss, so they left together. However, when the third uncle left, he also borrowed a lunch box from He Yuzhu to pack the leftovers.

Jiang Yan and his family did not lack this, so it was left to these three uncles to pack the goods.

"Old Liu, you sit down first and wait for me. I'll finish these paintings. Oh, by the way, there are cigarettes and tea on the table. You can do as you like." After entering the study, Jiang Yan pointed to the seat opposite his desk, facing his bangs. Got a hit.

After greeting Liu Haizhong, Jiang Yan immersed himself in drawing the drawing of the two-cylinder engine.

The engine designed by Jiang Yan is only 80CC, and the size is only the size of a book. It can be installed on a bicycle. This engine has low cost, simple structure, high stability, and strong low torque.

This engine also has the potential to pack twice the power into the same space, since it has twice the power stroke per revolution.The combination of lightness and twice the power gives it an amazing "push-to-weight ratio" compared to many four-stroke engines.

However, this same two-stroke engine cannot last as long as a four-stroke engine.A lack of precision lubrication systems means that two-stroke engine parts wear out more quickly.The engine's fuel consumption rate is high. After Jiang Yan's calculations, the small fuel tank he designed can't run about 20 kilometers with a full tank, but this is enough. His courtyard is only 5 kilometers away from Jiang Sirui's work. It can run four times with one full tank of gas.

This engine will produce a lot of pollution, which comes from two aspects.The first is the burning of lubricating oil.Lubricating oil makes all two-stroke engines fume to some extent, and a badly worn two-stroke engine can emit large clouds of oily fumes.The second reason is less obvious.Whenever a large amount of new air/fuel is injected into the combustion chamber, some of it leaks from the exhaust port. For this reason, Jiang Yan also specially designed a smoke exhaust port.

"Old Liu, bring this drawing over tomorrow and find an engineer with better skills to produce it." Jiang Yan directly placed the drawing he designed in front of Liu Haizhong. Not only did this drawing contain the engine Drawings, and some accessories to install on the bike.

"Mr. Jiang, don't worry, I will find the workers in our workshop to produce it tomorrow." Liu Haizhong picked up the drawings given by Jiang Yan and quickly promised.

"By the way, I designed this thing myself for my own use. How many materials and labor are needed? When the time comes, I will ask secretary Xiao Gong to send the money to you." Jiang Yan then said again.

After Liu Haizhong left Jiang Yan's study, Jiang Yan called Xu Damao in and told him about his preparations for filming. Xu Damao said that he would help Jiang Yan after he had arranged the farm affairs tomorrow.
